SYNOPSIS


#include <linux/module.h> 

caddr_t create_module(const char *name, size_t size);

DESCRIPTION

Note: This system call is present only in kernels before Linux 2.6.

create_module() attempts to create a loadable module entry and reserve the kernel memory that will be needed to hold the module. This system call requires privilege.

RETURN VALUE

On success, returns the kernel address at which the module will reside. On error -1 is returned and errno is set appropriately.

ERRORS

EEXIST A module by that name already exists.
EFAULT name is outside the program’s accessible address space.
EINVAL The requested size is too small even for the module header information.
ENOMEM The kernel could not allocate a contiguous block of memory large enough for the module.
ENOSYS create_module() is not supported in this version of the kernel (e.g., the kernel is version 2.6 or later).
EPERM The caller was not privileged (did not have the CAP_SYS_MODULE capability).

VERSIONS

This system call is only present on Linux up until kernel 2.4; it was removed in Linux 2.6.

CONFORMING TO

create_module() is Linux-specific.
